The Characteristics of RPM Pipe:

1)Lightweight, high strength and high stiffness;
2)Corrosion-resistant property;
3)Good hydraulic property;
4)Health property of RPM pipe;
5)Shock resistance;
6)Abrasive resistance;
7)Low temperature-resistant property;
8)Compliance against the environment.

Specifications:
1) Pressure class: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa;
2) Working pressure: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa;
3) Usual stiffness class: 2500N/m², 5000N/m², 10,000N/m²;
4) RPM pipe diameter: from DN25 to DN4000;
5) Each pipe length: within 12m;
6) The joint: the type of joint is socket-spigot with double O seal rings, flange joint, butt-joint and socket-spigot with adhering and others;
7) Fittings: in order to satisfy the different types of joint of pipe or pipeline, we can also produce many kinds of flanges, tees, reducers, manholes and other fittings to meet the different standards, such as GB, JS, HG, DIN and others;
8)Main mechanical property index of RPM pipe:Inner surface roughness coefficient: 0.0084;Barcol hardness: >40;

For special pressure class and stiffness grade can be designed especially.

                       PARAMETER OF RPM

 

Note: The serial parameter listed in the above table is only applicable for water supply or drainage.
Normally the pipe is not larger than DN400 doesn't add sand.


Application:
1.  Water supply project
-construction for urban and town water supply system;
-modification for urban and town pre-existing water supply pipe;
-farm irrigation;
2.  Drainage project
-sewers in urban area
-industrial drainage pipe
-Other drain pipes. RPM pipe can be considered to be used for drainage pipe for rain water and sewage in urban and towns , factory and mine, airport, seaport of coastal area or area reclaimed from the sea, because RPM pipe has the following advantage: sulfuric & alkali proof, occupy less area, heavy traffic, easy for transportation and less excavation and backfill.
3.  Water conservancy and power project
-Culvert project. RPM pipe can be used for feeding and drain the culvert on the cross point of the dams, channels and roads.
-Inverted siphon and
-Tunnel project
-Strengthen of the pre-existing culvert in the reservoir.
-Pressure pipe in hydropower station on mountainous regions.
-Sea water cooling pipe of power station
4.  Industry
- Conveying for corrosive fluid. For all industrial pipes which convey corrosive liquid and gas, such as the pipe needs to be of large diameter and anti-corrosive metal material, under this condition, RPM pipe is better.
-Pipe for petroleum industry. Used for the conveying of crude oil and natural gas, and the water return of oil field.
-Offshore construction pipe.
-Heat supply pipe. RPM pipe is excellent heat insulator, good property of insulation. It is suitable for conveying vapor and geothermal water etc.
-Ventilation and air supply pipe. It is used for large scale factory and mine, especially for ventilation of underground works. In large scale hotels, it can be used as the air supply pipe of central air-conditioning system.
